Arbroath, Angus, Scotland Original application June 1, 1933, Serial No.

673,892. Divided and this application November 22, 1933, Serial No..699,250. In Germany January 12, 1933 1 Claim. (01. 19-158) Thisinvention relates to sliver balling machines of the type in which thesliver ball or roll is wound on retractable arbor sections carried bypivoted arms jointly movable about a common 5 axis parallel to the axesof the arbor sections so as to swing upwards in the formation of theball, as described, for example, in the specification of Letters PatentNo. 1,791,076 dated 3rd February, 1931.

In the machine according to the invention which is a division of ourprior application Ser.

No. 673,892 filed 1st June, 1933, the sliver ball is confined during itsformation by non-rotatable cheek-plates, embraced by the arms, saidcheek plates being relatively immovable but being arranged to rise andfall together with the arbor sections, and to release the ball onretraction of the arbor sections.

The figure of the accompanying drawing is a side elevation of asliver-roll-forming or balling machine according to the invention.

As will be understood from reference to the drawing, the sliver ball orroll 8 is built up between a pair of spaced non-rotatable cheek plates13 which rise and fall together with the arbor sections 1.

The cheek plates 13 are constituted bya frame interposed between thearbor-carrying arms 2 and fixed to the hinged cross bracket 14 to whichthe arbor-carrying arms 2 are pivoted, the cheek plates 13 being formedwith aligned apertures 15 for penetration by the arbor sections 1.

During roll-building the cheek plates 13-rise with the arms 2, and, whenthe arbor sections 1 are withdrawn from the ball or roll 8 on completionof the latter, the combined weight of the cheek plates 13 and arms 2causes the frame to The cross bar 16 is arranged above the cheek plates13 the operation being such that, in the descent of the cheek plateframe, the cross bar 16 engages the periphery of the ball or roll 8 atthe rear thereof so as, in conjunction with the 9 driving roller, toeffect ejectionof the ball.

As shown the cross bar 16 is attached to the upper end of a lever 22pivoted at 23 at its lower end to the gable frame 5 of the machine andoperatively connected by a link 24 to an arm 25 uni- 10 tary with thecross bracket 14, the arrangement being such that, in the descent of thearms 2, the path of the cross bar 16 will be as indicated at 16-16 Whenthe ball is being ejected, incoming sliver 15 17 from the sliverdelivery rollers 18, 19 enters a reservoir 20 bounded by the cheekplates 13, so that momentarily, while ejection is taking place, surplussliver is caught in the reservoir 20 and effectively gripped between thearbor-sections 1 when they close for a re-start. 21 denotes a sliverguide.

What we claim is:--

A sliver balling machine comprising retractable arbor sections on whichthe ball is wound, a hinged cross-bracket, arms pivoted to saidcrossbracket and carrying said arbor sections, said arms being jointlymovable about a common axis parallel with the axes of said arborsections, nonrotatable cheek-plates fixed to said cross-bracket andembraced by said arms, said cheek-plates being relatively immovable butbeing arranged to rise and fall together with said arbor sections, saidcheek-plates serving to confine the ball ,during its formation andreleasing the ball on retraction of said arbor sections, an arm unitarywith said cross-bracket, an ejector for ejecting the finished ball frombetween said cheek-plates, and link and lever mechanism connecting saidejector to said arm.
